Determination of Regulatory Review Period for Purposes of Patent Extension; EMEND, 44033-44034 [E6-12573]

Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for CLINACOX (U.S. Patent No. 4,631,278) from Janssen Pharmaceutica N.V., and the Patent and Trademark Office requested FDA’s assistance in determining this patent’s eligibility for patent term restoration. In a letter dated October 4, 2000, FDA advised the Patent and Trademark Office that this animal drug product had undergone a regulatory review period and that the approval of CLINACOX represented the first permitted commercial marketing or use of the product. Thereafter, the Patent and Trademark Office requested that FDA determine the product’s regulatory review period. FDA has determined that the applicable regulatory review period for CLINACOX is 5,111 days. Of this time, 1,749 days occurred during the testing phase of the regulatory review period, 3,362 days occurred during the approval phase. These periods of time were derived from the following dates: 1. The date an exemption under section 512(j) of the Federal Food, Drug, and Cosmetic Act (the act) (21 U.S.C. 360b(j)), involving this animal drug product, became effective: April 25, 1985. FDA has verified the applicant’s claim that the date the investigational new animal drug application became effective was on April 25, 1985. 2. The date the application was initially submitted with respect to the animal drug product under section 512(b) of the act: February 6, 1990. The applicant claims January 31, 1990, as the date the new animal drug application (NADA) for CLINACOX (NADA 140–951) was initially submitted. However, FDA records indicate that NADA 140–951 was officially acknowledged and assigned the NADA number on February 6, 1990, which is considered to be the NADA initially submitted date. 3. The date the application was approved: April 21, 1999. FDA has verified the applicant’s claim that NADA 140–951 was approved on April 21, 1999. This determination of the regulatory review period establishes the maximum potential length of a patent extension. However, the U.S. Patent and Trademark Office applies several statutory limitations in its calculations of the actual period for patent extension. In its application for patent extension, this applicant seeks 1,096 days of patent term extension.

Furthermore, any interested person may petition FDA for a determination regarding whether the applicant for extension acted with due diligence during the regulatory review period by January 30, 2007. To meet its burden, the petition must contain sufficient facts to merit an FDA investigation. (See H. Rept. 857, part 1, 98th Cong., 2d sess., pp. 41–42, 1984.)

SUPPLEMENTARY INFORMATION: The Drug Price Competition and Patent Term Restoration Act of 1984 (Public Law 98– 417) and the Generic Animal Drug and Patent Term Restoration Act (Public Law 100–670) generally provide that a patent may be extended for a period of up to 5 years so long as the patented item (human drug product, animal drug product, medical device, food additive, or color additive) was subject to regulatory review by FDA before the item was marketed. Under these acts, a product’s regulatory review period forms the basis for determining the amount of extension an applicant may receive. A regulatory review period consists of two periods of time: A testing phase and an approval phase. For human drug products, the testing phase begins when the exemption to permit the clinical investigations of the human drug product becomes effective and runs until the approval phase begins. The approval phase starts with the initial submission of an application to market the human drug product and continues until FDA grants permission to market the drug product. Although only a portion of a regulatory review period may count toward the actual amount of extension that the Director of Patents and Trademarks may award (for example, half the testing phase must be subtracted, as well as any time that may have occurred before the patent was issued), FDA’s determination of the length of a regulatory review period for a human drug product will include all of the testing phase and approval phase as specified in 35 U.S.C. 156(g)(1)(B). FDA recently approved for marketing the human drug product EMEND (aprepitant). EMEND, in combination with other antiemetic agents, is indicated for the prevention of acute and delayed nausea and vomiting associated with initial and repeat courses of highly emetogenic cancer chemotherapy, including high-dose cisplatin. Subsequent to this approval, the Patent and Trademark Office received a patent term restoration application for EMEND (U.S. Patent No. 5,719,147) from Merck & Co., and the Patent and Trademark Office requested FDA’s assistance in determining this patent’s eligibility for patent term restoration.

Thereafter, the Patent and Trademark Office requested that FDA determine the product’s regulatory review period. FDA has determined that the applicable regulatory review period for EMEND is 2,513 days. Of this time, 2,332 days occurred during the testing phase of the regulatory review period, while 181 days occurred during the approval phase.

The applicant claims May 9, 1996, as the date the investigational new drug application (IND) became effective. However, FDA records indicate that the IND effective date was May 10, 1996, which was 30 days after FDA receipt of the IND. 2. The date the application was initially submitted with respect to the human drug product under section 505(b) of the act: September 27, 2002. FDA has verified the applicant’s claim that the new drug application (NDA) for EMEND (NDA 21–549) was initially submitted on September 27, 2002. 3.

SUPPLEMENTARY INFORMATION: The Drug Price Competition and Patent Term 
Restoration Act of 1984 (Public Law 98-417) and the Generic Animal Drug 
and Patent Term Restoration Act (Public Law 100-670) generally provide 
that a patent may be extended for a period of up to 5 years so long as 
the patented item (human drug product, animal drug product, medical 
device, food additive, or color additive) was subject to regulatory 
review by FDA before the item was marketed. Under these acts, a 
product's regulatory review period forms the basis for determining the 
amount of extension an applicant may receive.
    A regulatory review period consists of two periods of time: A 
testing phase and an approval phase. For human drug products, the 
testing phase begins when the exemption to permit the clinical 
investigations of the human drug product becomes effective and runs 
until the approval phase begins. The approval phase starts with the 
initial submission of an application to market the human drug product 
and continues until FDA grants permission to market the drug product. 
Although only a portion of a regulatory review period may count toward 
the actual amount of extension that the Director of Patents and

subtracted, as well as any time that may have occurred before the 
patent was issued), FDA's determination of the length of a regulatory 
review period for a human drug product will include all of the testing 
phase and approval phase as specified in 35 U.S.C. 156(g)(1)(B).
    FDA recently approved for marketing the human drug product EMEND 
(aprepitant). EMEND, in combination with other antiemetic agents, is

    FDA has determined that the applicable regulatory review period for 
EMEND is 2,513 days. Of this time, 2,332 days occurred during the

FDA records indicate that the IND effective date was May 10, 1996, 
which was 30 days after FDA receipt of the IND.
    2. The date the application was initially submitted with respect to 
the human drug product under section 505(b) of the act: September 27, 
2002. FDA has verified the applicant's claim that the new drug

September 27, 2002.
    3. The date the application was approved: March 26, 2003. FDA has
